Description

Intermittent failure in ExecutionCommandWrapperTest:

Running org.apache.ambari.server.actionmanager.ExecutionCommandWrapperTest
Tests run: 3, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 14.452 sec <<< FAILURE! - in org.apache.ambari.server.actionmanager.ExecutionCommandWrapperTest
testExecutionCommandHasVersionInfoWithoutCurrentClusterVersion(org.apache.ambari.server.actionmanager.ExecutionCommandWrapperTest)  Time elapsed: 0.024 sec  <<< ERROR!
org.apache.ambari.server.ServiceNotFoundException: Service not found, clusterName=c1, serviceName=HDFS
	at org.apache.ambari.server.actionmanager.ExecutionCommandWrapperTest.testExecutionCommandHasVersionInfoWithoutCurrentClusterVersion(ExecutionCommandWrapperTest.java:293)

is caused by dependence on order of execution of test methods.

Steps to reproduce:

1. Disable testGetExecutionCommand() to simulate "wrong" order of execution
2. Run ExecutionCommandWrapperTest

Result:

Running org.apache.ambari.server.actionmanager.ExecutionCommandWrapperTest
Tests run: 2, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 7.4 sec <<< FAILURE! - in org.apache.ambari.server.actionmanager.ExecutionCommandWrapperTest
